ROLLER-TENSION FOR SELF-BINDING HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 407,634, dated July 23, 1889.

Application filed February 15 1886. Serial No. 191,945. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. EON-TE, a citizen of the United States, and a resident of the city of Cincinnati, Hamilton county, and State of Ohio, have invented certain new and useful Improvements in Roller-Tensions for Self-Binding Harvesters, of which the following is a specification. My invention is intended for use in connection with that class of machines known as self-binding harvesters. In these machines the twine usually passes directly from the twine-box to the needle of the binder. The twine, however, is apt to become kinky and to feed too fast to the needle, both interfering with the proper action of the binder.

To avoid these defects is the object of my invention.

In the accompanying drawings, Figure 1 is a side elevation of my improved tension. Fig. 2 is an elevation of the other side of the device. Fig. 3 is a top View, and Fig. at is an elevation, of the left-hand end of the device as it appears in Fig. 1.

The four standards B B C 0 rise from the base-plate A and support the rollers D on the axles (Z. The cylindrical surface of each roller is provided with one or more annular grooves d. Preferably these grooves d are three in number on each roller, as shown in the drawings. Each of the rollers D, on the face adjacent to the standard B, is provided with a cylindrical projection or drum D, concentric with the aXis of the roller. The brake E is provided with two depressions to fit accurately the curved surfaces of the drums D,.

and rests on both of them, as shown. The cross-piece B, resting 011 the tops of the standards B, projects somewhat within the inner edge of these standards, and forms a support for the adjusting screw F, which screws through this cross-piece and bears against the top of the yoke E. A cross-piece C is preferably provided, connecting the tops of the standards 0 C. An arm 0 extends horizontally from one of the standards 0 somewhat beyond the edge of the roller D. The arm 0 is provided at its free end with an eyelet or guide G. The projection H is attached to the base-plate A, and carries an eyelet or guide h of sufficient size to pass knots and lumps, such as are formed on common binding-twine. The eyes in the guides G and II are funnel-shaped, the diminishment in size being in the direction in which the twine is to'rnove through the eyes.

The device may be attached to the bindingmachine at any convenient place between the twine-box and the needle. Preferably it is attached to the twine-box itself. The end of the twine, as it comes from the twine-box is passed through the eyelet hand then passed around the rollers D, the twine resting in the grooves d, as shown in the drawings. The twine is then passed through the eyelet G, whence it is led to the needle. The tension of the twine as fed to the needle is regulated by the screw F, which increases the tension as it is forced down against the brake E. Besides regulating the tension of the twine, the device straightens out all kinks which form in the twine and prevents their subsequent formation.

While the various features of my invention are preferably employed together, one or more of said features may be employed without the remainder, and in so far as applicable in connection with roller or other tensions than the one specifically herein set forth.

What I claim as new and of my invention,

and desire to secure by Letters Patent, is- I 1. In a tension device for self-binding harvesters, the grooved rollers, each having a hub or drum D, the independent brake-piece E, resting upon the said hubs, and at the point where it so rests being hollowed to receive the hub, and the set-screw F, engaging a stationary support and pressing against the brake-piece E at a point between the hubs, substantially as and for the purposes specified.

In a tension device for self-binding. harvesters, the grooved rollers and hubs orsdrums D, and independent brake piece resting against the said hubs, and at the point where. it so rests being hollowed to receive the hub, and the set-screw F, engaging a stationary support and pressing against the brake-piece E at a point between the hubs, anddeliveryguide G, having the funneled-shaped eye,
